Vascular cambium is a crucial growth layer in stems and roots, responsible for producing xylem and phloem in plants. It originates from the maturation of procambium cells, differentiating into storied and non-storied cell types. It plays a vital role in secondary growth by generating new wood in woo

Root and stem in plants form a continuous structure with a transition region between them. The transition involves twisting and inversion of xylem strands, leading to variations in vascular bundles. Eames and Mac Daniels identified different types of vascular transitions in dicots and monocots, each

Plant mineral nutrition involves the absorption and translocation of ions across roots. Salts are absorbed passively and actively, with ions moving into the root's apoplasm via free diffusion. The Casparian strip in endodermal cells acts as a barrier, allowing ions to pass only through the protoplas
